You don't need a swift kick. What you need is to get your "healthy" mojo back in gear. Think about what motivated you in July 2010. What made you decide you need to make a change ? That's where you restart your efforts. Then you do the same things, you start with small changes. You take baby steps literally and figuratively. You don't try to do everything at once or you will end up frustrated.
So, if you know you're eating a little too much junk at night, then you have two choices. Either you toss the junk out of the house (out of sight, out of mind) OR you put the treats into portion controlled baggies.
As you know, you can have treats as long as you are mindful of the portions. However, if you don't think you can portion control the treats, then out they go. If they aren't there to eat, that one less thing to worry about. instead, go out and buy some fresh fruit. Whenever you feel an urge to have a snack in the evening, have a couple of pieces of fresh fruit. That's a better option than digging into the junk AND as you eat better, you'll start to feel better.
So, no more beatings, the beatings aren't productive. Instead, let's starting doing things that ARE productive !!
